What is the command to modify file name in Linux?
There are two commands for modifying file names in Linux: 1. mv command, which can not only rename files, but also move files or folders. Modify the syntax "mv [parameter] old file name, new file name"; 2. The rename command can be used to change file names in batches by string replacement. The syntax is "rename [parameter] old file name, new file name".
#The operating environment of this tutorial: CentOS 6 system, Dell G3 computer.
To rename files or directories under Linux, you can use the mv command or the rename command. Here we share how to use both.
1. Use the mv command
The mv command can both rename and move files or folders.
mv [參數(shù)] 舊文件/目錄 新文件名/目錄
Example: Rename directory A to B
mv A B
Example: Move the /a directory to /b and rename it to c
mv /a /b/c
In fact, in text mode To rename a file or directory, just use the mv command. For example, if you want to rename a file named abc to 1234:
mv abc 1234
Note, if there is also a file of 1234 in the current directory, This file will overwrite it.
How to use the mv command to rename multiple files?
The mv command can only rename one file at a time, but it can be used with other commands such as find in a bash for or while loop to rename multiple files.
Example: How to rename all .html files in the current directory, changing the .html extension to .php by using a bash for loop.
for f in *.html; do
mv -- "$f" "${f%.html}.php"
doneLet’s analyze the code line by line:
● The first line creates a for loop and traverses a list of all files.html.
● The second line applies to each item in the list and moves the file to a new one replacing .html with .php. The section ${file%.html} uses the shell parameter extension .html to remove the part from the file name.
● done indicates the end of the loop segment.
We can also use the command find in combination with mv to achieve the same function as above.
find . -depth -name "*.html" -exec sh -c 'f="{}"; mv -- "$f" "${f%.html}.php"' \;The find command uses this switch to pass all .html files ending in the current directory mv to the command -exec one by one. The string {} is the name of the file currently being processed.
As you can see from the above example, using the mv command to rename multiple files is not an easy task as it requires a good understanding of Bash scripting.
2. Use the rename command
The rename command uses string replacement to batch change file names.
Rename a single file
# 將main1.c重命名為main.c rename main1.c main.c main1.c
rename supports wildcards
? 可替代單個字符 * 可替代多個字符 [charset] 可替代charset集中的任意單個字符
There are these files foo1, …, foo9, foo10, …, foo278
If you use rename foo foo0 foo?, the files from foo1 to foo9 will be renamed to foo01 to foo09, the renamed file is just a file with a 4-character length name, and foo in the file name is replaced with foo0.
If you use rename foo foo0 foo??, all files from foo01 to foo99 are renamed to foo001 to foo099, and only files with names of 5 characters in length are renamed. foo is replaced with foo0.
If you use rename foo foo0 foo*, all files from foo001 to foo278 are renamed to foo0001 to foo0278, and all files starting with foo are renamed.
If you use rename foo0 foo foo0[2]*, all files from foo0200 to foo0278 are renamed to foo200 to foo278, and foo0 in the file name is replaced with foo.
rename supports regular expressions
# 把文件名中的AA替換成aa rename "s/AA/aa/" * # 把.html 后綴的改成 .php后綴 rename "s//.html//.php/" * # 把所有的文件名都以txt結(jié)尾 rename "s/$//.txt/" * # 把所有以.txt結(jié)尾的文件名的.txt刪掉 rename "s//.txt//" *
By default, the rename command will not overwrite existing files; but passing the -f parameter will Allows overwriting of existing files.
rename -f 's/.html/.php/' *.html
Common examples of using the rename command
Replace spaces in file names with underscores
rename 'y/ /_/' *
Convert file names Convert the file name to uppercase for lowercase
rename 'y/A-Z/a-z/' *

How does resource usage (CPU, memory) differ between Linux and Windows?
Jun 05, 2025 am 12:13 AM
Linux and Windows have their own advantages and disadvantages in CPU and memory usage: 1) Linux uses time slice-based scheduling algorithms to ensure fairness and efficiency; Windows uses priority scheduling, which may cause low-priority processes to wait. 2) Linux manages memory through paging and switching mechanisms to reduce fragmentation; Windows tends to pre-allocate and dynamic adjustment, and efficiency may fluctuate.
How does the cost of ownership differ between Linux and Windows?
Jun 09, 2025 am 12:17 AM
Linux's cost of ownership is usually lower than Windows. 1) Linux does not require license fees, saving a lot of costs, while Windows requires purchasing a license. 2) Linux has low hardware requirements and can extend the service life of the device. 3) The Linux community provides free support to reduce maintenance costs. 4) Linux is highly secure and reduces productivity losses. 5) The Linux learning curve is steep, but Windows is easier to use. The choice should be based on specific needs and budget.

How to install Linux alongside Windows (dual boot)?
Jun 18, 2025 am 12:19 AM
The key to installing dual systems in Linux and Windows is partitioning and boot settings. 1. Preparation includes backing up data and compressing existing partitions to make space; 2. Use Ventoy or Rufus to make Linux boot USB disk, recommend Ubuntu; 3. Select "Coexist with other systems" or manually partition during installation (/at least 20GB, /home remaining space, swap optional); 4. Check the installation of third-party drivers to avoid hardware problems; 5. If you do not enter the Grub boot menu after installation, you can use boot-repair to repair the boot or adjust the BIOS startup sequence. As long as the steps are clear and the operation is done properly, the whole process is not complicated.
How to enable the EPEL (Extra Packages for Enterprise Linux) repository?
Jun 17, 2025 am 09:15 AM
The key to enabling EPEL repository is to select the correct installation method according to the system version. First, confirm the system type and version, and use the command cat/etc/os-release to obtain information; second, enable EPEL through dnfinstallepel-release on CentOS/RockyLinux, and the 8 and 9 version commands are the same; third, you need to manually download the corresponding version of the .repo file and install it on RHEL; fourth, you can re-import the GPG key when encountering problems. Note that the old version may not be supported, and you can also consider enabling epel-next to obtain the test package. After completing the above steps, use dnfrepolist to verify that the EPEL repository is successfully added.
How does Linux perform compared to Windows for web server workloads?
Jun 08, 2025 am 12:18 AM
Linux usually performs better in web server performance, mainly due to its advantages in kernel optimization, resource management and open source ecosystem. 1) After years of optimization of the Linux kernel, mechanisms such as epoll and kqueue make it more efficient in handling high concurrent requests. 2) Linux provides fine-grained resource management tools such as cgroups. 3) The open source community continuously optimizes Linux performance, and many high-performance web servers such as Nginx are developed on Linux. By contrast, Windows performs well when handling ASP.NET applications and provides better development tools and commercial support.
